To all whom it may concern:

Be it known that I, WALTER G. Wrrnnns, a citizen of the United States, residin at- Atlanta, in the county of Fulton and t tale of Georgia, have invented certain new and uselul Improvements in Sash-Weights; and I do hereby declare the following to be afull, clear, and exact descri tion of the invention, such as will enable ot lers skilled in the artto which it appertains to make and use the some.

'1' his invention relates to im roved sash weights, and has for an object t e provision of a jointed sash weight that is so mounted as to not become un ointcd during use.

Another object in view is the provision of a sash weight arranged with a plurality of links formed with engaging means that w1ll prevent the disengaging of any of the hnks until the links are brought. to a predetermined osition.

A sti l further object of the invent-ion is the provision of sash weights formed of links orrangcd with a bifurcated end having projections extending therefrom and an end formed with a tongue hsvin" ways positioned therein, the bifurcated end of one link being adapted to have the tongue of the adjoining link ositioned therebetween, and the projection rum the bifurcated end positioned in the ways in the tongue.

With these and other objects in view, the invention comprises certain novel constructions, combinations and nrrane'ements of parts that will be hereinafter full;- described and claimed.

In the accompanying clmwing:-Figure 1 is a side ElBYtlt-IOXI of two links joined togcthor for for-min a sash weight. Fig. 2 is a to Ian view A? the weight shown in Fig. l. ig. 3 is a side elevation of two links on a reduced scale, the same being shown in a. position ready for securing together or a removal. Fig. 4 is a fragmentary sectional view of one end of Fig. 1 approximate-l on line 44. Fi 5 is a. view similar to 1g. 4 disclosing a. s lght modified construction.

In the construction of sash weivhts, particularly flexible sash Wei hts mode from a plurality of pieces joine' together, it. has won found very desirable to make the some so as to be easily joined and disjoined, and when joined to be locked in a certain sense.

Referring more particularly to the drawing, 1 and 2 indicate links which have bifurcated extensions 3-3 on one end and on the opposite end a tongue 4 formed with Wtys 5 and 6 and journal portions 7 and N.

The opening 9 between Injections 3*3 is formed rounded at 10, as c early seen in Figs. 1 and 3, so that when any slack is brought. upon the weight the upper links cannot be deranged or moved out of place. as the tongue 4 of each of the upper links comes in contact with the upper edge 11 of the res ctive links or against the sides of the bearings.

of 'ournal portions 4 and 8.

he hearings or journal portions 7 and S are adopted to extend only partially through the tongue 4, as clearly seen in Fig. 4 and are adapted to receive journal members 12 and 13 projecting from the inner faces of the extension 3-3. The projections 12 and 13 may be cylindrical or beveled, as may be desired.

\Vhen it is desired to use several of the links for lormiu a complete weight of any desired size alin as 2 is laced in position, as shown in Fig. 3, over lin 1 and the lugs or projections 12 and 13 are permitted to pass through ways 5 and 5 until they reach the bearin s 7 and S, then the link 2 is moved pivots y upon members 12 and 13 until the same is in position as shown in Fig. 1. "hen in this position link 2 cannot be removed, and in order to be removed must be turned substantially to the position shown in By this construction and arrangementit will be observed that none of the links can become unfastcned or detached while in operation. Each of the extensions 3-3 are rounded at 14 in order to permit proper pivotal movement of the respective links. The upper ends of extensions 33 are also spaced away from the shoulder portion 15 of the link when the respective links are in their correst position for operation. This permits a. slight up and down movement of the respective links, which acting together with the pivotal movement of the respective links permit free action of the respective parts of the entire weight, but by the particular construct-ion and arm-n merit of the curved seat or bottom 10 of t. o hollowed out portion 9 the respective links cannot come unfastoned without being moved to u )osition substantially as shown in Fig. 3. n constructing the journal members 12 and 13 in the ways 5 and 6 together with the journal bearings 7 and 8 it. is to be noted that the tongue 4 is not weakened by an aperture passing therethrough, nor a slot passing from the I plurality of units, each unit being provided edge of the weight to the aperture, but sunwith a tongue at one end sand tongue having ply depressed portions are provided for the ourna bearings and depressed ways are provided for permitting the members 12 and Y 13 to enter into the journal bearings. A web 16 is thus retained in ton ue 4 that then oughly braces and sustains the tongue portion.

In Fi 5 will be seen a slight modification in whicl a tongue 4 is presented, having ways 5 and 6'. The ways 5 and 6 mer e into an aperture 17 that passes entire y through the tongue 4. Tins aperture 17 is adapted to take the place of the bearings 7 and S.

The ways 5 and 6 and also ways 5' and 6,

together with the bearings 7 and 8, and also 17, form an L-shaped way for receiving and accommodating the journals l2 and 12 In arranging a weight formed accordm to the present invention it will be observed hat the same forms a flexible wei lit and yetone having substantially the weight of astraight bar or rod by reason of thecompa-ctness of the construction, onlysuffiolent space being left between the various arts to permit proper movement. It will e noted in this connection that where one link or unit is cut placed accidental] out or cut away the adjoining link or unit is formed with members for filling in the cut out or cutaway portions just mentioned so as to fill substantially all the space occupied by the weifl'ht.

What I claim is 1. In a sash weight, a weight formed of it its end semi-circular, and a bifurcated portion at the opposite end, a hollowed out portion between the arms of the bifurcation formed upon the are of a circle, said tongue being formed with 'ournal bearings and ways for perniittim the caring members to be inserted in said journal bearings, and said bifurcated portion being formed with journals extending therefrom and adapted to enter the bearings of the tongue of an adjoining link, the tongue of the adjoining link when inserted into said bifurcation being prevented from accidental removal by the curved bottom of the opening between the arms of the bifurcation.

2. In a sash weight, a weight formed of a plurality of units pivotally secured together, each link being formed of a bifurcated end and a tongue, the tongue of one link being adapted to fit between the furcations of the adjoining link, the hollowed out portion between the respective bifurcated ends, havin its bottom formed arc-shaed and the ends oi the respective tongues eing formed areshaped, the arc-shaped construction of the bottom of the opening of the bifurcations preventing the tongue from becoming dis In testimony w iereof I have affixed my signature in presence of two witnesses.
